Richard Gibbs, prosecuting at Birmingham Crown Court, said Mr Brown had gone to stay at a friend’s flat at Avon House on March 8. Sagheer was already there and asleep.

The following morning, when they were left alone, Sagheer demanded cigarettes from Mr Brown, whose mobility was limited because of his condition,

Mr Gibbs told the court: “(Sagheer) demanded to look n the complainant’s bag and removed £45 and demanded to know whether his bank account was in funds.

“He held up a card and demanded to know the PIN number and threatened to stab the complainant if the PIN was wrong.”

Sagheer also threatened to strangle Mr Brown with a sock, burn him with an iron and pour boiling water over him if the wrong PIN number was given.

Mr Gibbs added: “He then told the complainant he was going to the cash machine with the card, he would withdraw £20 to buy a phone top-up, vodka, cigarettes and weed.”

It was only when left alone that Mr Brown was able to call the concierge of the building to raise the alarm.

When arrested Sagheer denied the offence and claimed the victim had made sexual advances towards him.

In an impact statement Mr Brown said he was no longer able to spend time in groups of people, suffered panic attacks and was no longer the same person.

William Dudley, defending, said Sagheer had been tackling his drink and drug issues since being held in prison on remand. He said: “His alcohol and substance issues have been treated effectively, he is sorting himself out really rather successfully.”

Recorder Richard Benson said Sagheer had “terrorised” his victim. He said: “You threatened to stab him, throw boiling water over him, burn him with an iron and strangle him, all because you wanted his debit card.

“He had an outgoing, gregarious personality, you took that away from him and left him not only in a physically disabled state, but also without that shining personality which helped him through that disability.

“I am told you demonstrated remorse, it is not clear if you were sorry for what happened to Mr Brown, or what has happened to you.”

In a separate hearing Sagheer was jailed for four weeks by magistrates after pleading guilty to stealing a remote control helicopter from a Maplin store in Solihull.
